To all whom 'it may concern:

Be it known that I, JOHN ANTHONY, a citizen ofthe United States, residing at Attleboro, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Reinforced Puncture-Proof Tires; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in tires.

Une object of the invention is to provide a tire having arranged therein a puncture proof reinforcement by means of which the tire will be effectually protected at the points where the greatest strain occurs.

Another object is to provide a reinforcement of this character' which will be strong and durable in construction, efficient and reliable in operation and which will .not interfere with the elasticity or the yieldingaction of 'the tire.

With these and other objects in view, the

invention consists of certain novel features of construction, combination and arrange .nient of parts as will be more fully described and partlcularly pointed outl 1n the apl pending claim.

ln the accompanying drawings: .Figure l is a side view of a. portion of my ii'nproved tire with parts broken away and in section; lfig. is a cross sectional view of the same;

" ll`ig. -3 is a cross sectional view on an enlarged scale of a portion of one side of the tire showing more Clearly the construction and arrangement of the reinforcements therein and the construction and arrangement of the filling or binding strip for this side of the tire; lfig. #l is an enlarged plan View of a portion of the woven wire rein forcing fabric showing more clearly the construction and arrangement of the coils of bfi the fabric; Fig. 5 is a detail cross sectional View of the same; Fig. 6 is a detail perspective View of a portion of one of the binding and filling strips employed in connection with the reinforcement for holding the folded or double edges of the same and the adjacent port-ions of the tire in shape to receive the flanges of cleneher rims.

ln the embodiment of the invention shown in the accompanying drawing, 1 denotes the outer covering or layer of the tire, said cov ering or layer l being preferably formed of rubber. Firnlly secured to the inner side of the rubber coveringor layer l is an outer and 'thus readily yield or give to the movef ment of the latter when pressure is applied thereto. l l

The woven wire reinforcing sheet or strip 4 is folded outwardly upon itself at the inner edges of the tire and the folded edges of the strip or sheetextended upwardly in engagement with the outer sides of the main portion of the sheet thereby providing a double construction for the inner portion or sides, of the tire. As is wellA known the greatest strain is applied to the inner p0rt-ions of the sides of a pneumatic tire, and it is at this point that most blow-outs occur. By doubling` my improved reinforcement as herein shown and described the sides of the tire are greatly strengthened and enabled to eifectually resist the strain or pressure applied thereto.

VVhen the. tire is to be employed in connectiony with clcncher rims, the inner folded or doubled edges of the reinforcement are bent to conform to the shape of the clenching flanges of the rim and said folded or doubled edges and the portions of the tire coverii'lg the same are supported or held ill/shape to receive the clenching flanges of the rim by means of filling or binding members 6, said members being constructed in the form of woven wire strips having their edges bent inwardly in the form of coils 7 whereby said binding or filling members are given asub stantially elliptical shaped formin cross sec tion and will be flexible and will readily conform to the circular shape of the tire and will approximately lill the spaces formed by the folded and bent inner edges of the reinforcement and will suith .r said folded or bent ends and the adjacent portions of the llC tire to receive the clenching flanges of the rim whereby the tire will be effectually secured thereto.

While my improved reinforcement is herein shown and deseribed as being arranged between the inner and outer linings of the tire it is obvious that the reinforcement may be otherwise arranged as for' instance, be-

. tween the outer lining and the oute` rubber covering or embedded in said out-er rubber covering o r sald relnfo'rcelnent may be arranged between the inner lining and the inf ner tube ofv the tire.

From the foregoing description taken in connection with thepaccompanying drawingsthe construction and operation of the inventages of the invention as defined in the ap; pended claim.

Having thus described my invention, what I claim is:

In a tire a flexible reinforcing stri'ii'liavi ing its inner edges folded outwardly ulpon the outer 'sides of the strip and bent to form' longitudinal passages,' binding members adapted to bev engaged with said passages, said members being formed from woven wirel strips-having their edges bent 'mwardly, in the form of coils whereby a'substantially elliptically shaped flexible body.

is provided for said binding members.

In testimony whereof I have hereunto set my'hand in presence of two subscribing witnesses.

JOHN ANTHONY.
